PHOTOS: New Moon Stars Hit Comic Con

Robert Pattinson, Kristen Stewart and Taylor Lautner faced the flash of photographers and answered reporters’ questions at Comic Con today, as the Twilight mega stars hit the red carpet and headed to a press conference. And although Rob and Kristen appeared a little cold towards each other at first, an eyewitness tells OK! the twosome warmed up as they answered questions about the new flick.

Robsten appeared to at first “have their guard up,” says the onlooker, but body language doesn’t lie — when asked about their chemistry, Rob blushed and a smile lit Kristen’s face.

As the three loosened up, Kristen’s attitude towards both Rob and Taylor “was very playful” — when they were asked a question, she seemed to be teasing them and they made faces at each other.

Interestingly enough, Rob’s favorite scene is one of the saddest in the book (spoiler alert!) — when Edward leaves Bella.

“I think my breakup scene was my favorite scene,” he revealed to reporters. “Hopefully it will come off as having quite a few more levels than the relationship in Twilight.”
